IMAP and POP3 are two common protocols used by email applications to receive messages from a mail server.

The best option depends on how you use your email account.

What is IMAP?

IMAP keeps your email messages synchronized with the mail server.

When you read, delete or move a message on one device, the change can also appear on other devices connected to the same account.

IMAP is usually a good choice if you:

- Use email on multiple devices.
- Access the same mailbox from a computer, phone and tablet.
- Want folders and message status to remain synchronized.
- Want messages to remain stored on the mail server.

What is POP3?

POP3 is designed primarily to download messages from the server to an email application.

Depending on the configuration, messages may be removed from the server after they are downloaded or may remain on the server for a defined period.

POP3 may be useful if you:

- Mainly use one device for email.
- Prefer to store messages locally.
- Need to reduce the amount of email stored on the server.
- Have a specific workflow that requires local message storage.

Which should you choose?

For most users who access email from multiple devices, IMAP is generally the more practical option.

POP3 may be suitable for users who primarily work from one device and prefer local email storage.

Important

The available protocols, ports and security settings depend on your hosting and email configuration.

Before configuring an email application, check the correct incoming and outgoing server settings for your account.
